define(&#39;THIS_PATH&#39;, dirname(THIS_FILE)); // 当前路径,可修改
define(&#39;Cover&#39;, &#39;new&#39;); // 是否直接覆盖本文件(改为 true 不加单引号,危险),建议写入其他地址(相对于当前路径)
define(&#39;DS&#39;, DIRECTORY_SEPARATOR); // Linux改为&#39;/&#39;,Windows为&#39;\\&#39;
define(&#39;ICONV&#39;, &#39;UTF-8&#39;); // 最终转换编码格式
function eachFile($path, $files = [])
{
    if (Cover !== true && $path == THIS_PATH . DS . Cover) {
        return $files;
    }
